To all whom it may concern:

Be it known that I, AUSTIN H. STEWART, a citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have in vented certain new and useful Improvements in SpaceElectromechanical Synchronizing Means, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to space-electro-mechanical means, which, whileparticularly useful in the synchronizing of timepieces, isalsosusceptiblc of utilization for many other purposes, instances ofwhich are the simultaneous transmission of a given signal or alarm to aplurality of stations, the operation of bells or chimes or thecontrolling of motors'ior other mechanism by the actuation of a singlecontroller, as will be apparent from the detailed descriptionhereinafter when read in connection with the accompanying drawingsforming part hereof and wherein a preferred embodiment of the inventionis illustrated for the purpose of facilitating the impartation of aclear and full understanding of the underlying principles of theinvention and the many novel details of structural parts andcombinations of elementsincident to a perfected con struction forcarrying the in-,ven ion into practical effeet. It is to be expresslyund stood, however, that, although certain disclosures of s )ecialmechanism are made herein, it is in no sense the intention to be-limitedto any specific features of construction thereof, but rather'that theirequivalents may be resortedto, except in-so-far as any such features maybe specifically included in the hereto appended claims.

The invention has for an object and comprehends the employment insynchronizing mechanism of space electricity, or what are commonly knownas the Hertzian waves or vibrations created bya suitable transmittingmedium, conveniently a Ruhmkorff induction coil, for

' transmitting impulses, so-called, to properly influence or affect acoherer, whichis injturn operatively associated with the electrical andmechanical partsnecessary in an apparatus of the character underconsideration. While the term Hertzian waves is used herein, it isbecause said term is believed to be the broadest manher, at presentknown, of expressing that element or medium which operates through spacefrom a transmitting station to effect a perceptible result at areceiving station, and this observation is made that the term inquestion may be appreciated as one of cornprehensive rather thanrestricted. application.

In securing practical results by the use of the present invention novelmechanical contrivances have been devised, prominent among which are theconstructions of the coherers; the means-for agitating and decoheringthe particles of said coherers; the mcansfor cutting in and out ofcircuit the winding and hand-setting dcvices of a clock, and theconstruction of the hand-setting means, all of which will more fullyhereinafter appear.

In the drawings, the invention is illustrated as embodied in a clocksynchronizing system, the several views of which are as follows:Figure 1is a face view of the clock, adapted to be affected by the Hertzianwaves, the forepart of the casing and the dial being removed; Fig. 2 isa side elevation of the time-mechanism proper and the immediatelyrelated parts; Fig. 3 is an enlarged view of the upper portion of 1,parts being broken away to bring to sight portions of the interiorconstruction; Fig. 4 is a detail elevation of the circuits controller,and parts of the winding means; Fig. 5 is a similar view of the circuitscontroller, the parts thereof being shown in a position different fromthat of the preceding figure; Fig. 6 is a cross-section on the line 6-6,Fig. I, looking downward in the direction of the arrow; Fig. 7 is a planview of the coherer and its support shown in the preceding figures; Fig.8 is a-longitudinal horizontal section of said coherer and support; Fig.9 is a transverse sectional view on the line 99 of Fig. 7 looking in thedirection of the arrow, to show particularly the star-wheel agitator fordecohering. the particles of the coherer; Fig. 10 is a diagrammatic viewof the wiring at the transmitting station of the system; Fig. 11 is acorresponding view of part of the wiring associated with the clock, orperhaps more properly stated,

the receiving station of the system; Fig. 12 is a similar view of thewiring at both the transmitting and receiv ing stations, that ofthereceiving' station being shown more in detail as compared with Fig.11; Fig. 13 is atop plan view of a slightly modified form of cohercrgasection being taken through the pendulum stem; Fig. 14 is a longitudinalvertical section of the same, a fragment of the pendulum stem beingshown in edge elevation; Fig. 15 is atransve'rse section of Fig. 13looking in the direction of the arrow; and Fig. 1.6 is a perspectiveview of a still further form of the coherer.

Referring more specifically to the drawings, A designates the back-boardor plate of the clock to which the operating parts are affixed; B is theframe of the clock-.

works; C the ordinary clock train; and D D, respectively, the minutesand seconds-hands (Fig. 2).

-E indicates in a general way the winding mechanism which it isunnecessary to here define in detail inasmuch as the same is of thecharacter fully disclosed in United States Letters Patent No. 308,521,.issued to Chester H. Pond, November-25, 1884, and embraces no part ofthe present invention save the switch or circuit controller for throwingthe same into and out of operation, andthis feature will be pointed outherein.

Mounted upon the .main operating shaft or arbor which carries theminutes-hands is a circular metallic conducting disk f, (Figs. 3, 4 and5) from the front surcuit will .be completed through a wire f inelectrical front surface of the disk f is remote relative to thelocaterminals suitably inserted into and secured at the ends face ofwhich a pin f projects in such a manner that at periodical times duringits travel thesame will engage the freelend of. a metallic rod f andelevate it upon its pivot f until said rod shifts into contact with aspring terminal g .of a local circuit hesignated by full-linearroWs(Fig.' 12) to be revgrted to hereinafter. This circommunicationwith batteries G, said rod f branch Wire 9 and the winding mechanism Ewhereby the winding mechanism will be actuated in the manner set forthin the hereinbefore referred to patent, the return wire running. back tothe batteries G being represented Occupying a plane parallel to that ofthe rod f 2 is an arm H also pivoted at f and arranged to project at itsfree end into the path of circular movement of a pinh projectingoutwardly from'thcrar face of the disk f. As the disk rotates the. pin helevates the arm H in a manner similar to the elevation of the rodfuntil the metallic conducting surface h on the upper edge of said armcomes into contact with the spring terminal 9 of the local circuitdesignated by dotted-line arrows (Fig. 12), when said circuit will becompleted through' the wires f f and g and the hand-setting mechanism. l

The spring terminals g, g are electrically connected to one and the sameload (f they being formed by bifurcating the free end of a leaf spring g(Figs. 4 and.5) supported in the slitted end of a fixed cleat g.Thetendency of these terminals is to bend or curl in a downwarddirection, and to maintain them at the proper elevation a less resilientleaf g is supported by the cleat g in a way to underlie the terminal andbe adjustable longitudinally thereof in an obvious manner.

It will be noticed'that the location of the pin f 1 on the "tion of thepink on the rear surface thereof so that the rod f -and arm H'- inust bealternately actuated rather than simultaneously, which enables theutilization'of a single relay for-controlling both thelwind ing andsetting mechanisms. It is also to .be noted that the arm H is composedof bone or other non-conducting or insulated material to overcome anydanger of short circuiting between said arm and the rod f the latterbeing formed of metal to serve as a conductor.

In those portions of the description just completed, it has been assumedthat the local circuits are normally intact-excepting at the pointwhere-the terminals and g abut the rod f and arm H, but such is nottrue/inasmuch as these circuits are also normally openby reason i of thenon-attraction of the armature p of a-magnet P in a relay circuit P(Figs. 11 and 12), said relay including acoherer which Will now bedefined, reference being had more particularly to Fig. 1, and Figs. 6,7, Sand 9.: I designates a tube conveniently .of'glass and i are the ofthe tube, while t" represents the metallic granulated or powderedsubstance intermediate said terminals,

tions of nickel and silver 'filings While the coherer is under theinfluence of Hertzian waves this metallic substance cohercs as usual,and to decohere the same it has heretofore been suggested to tap, shakeor turn over i the tube which contains the particles, but as comparedwith such methods, that designed for the present purseases I poses, t'.e.,means operating on the interior of the tube for agitating andseparating the particles, is a. decided improvement.

Passing longitudinally through one of the terminals 1 and rotatabletherein is a shaft k carrying at its inner end a star-wheel agitator K,both said shaft and agitator being formed of ivory or othernonconductive material. The star wheel or other agitator, for the samemay be different shapes, is arranged within the space between theterminalsi together with the metallic powder or su b-. 7 5 stance, andis operated through the medium of a crank l rigidly fastened to theouter end of the shaft lc and arranged to be oscillated by the pendulumstem L as the latter vibrates from right to left in the performance ofits regular function, an adjustable clip I embracing said stem andprojecting at its ends slightly forwardly there from so as toalternately engage and swing the crank l in the direction of movement ofthe pendulum. To secure thdbest results the crank- Z should be initiallycentered between the ends of the clip t (Fig, 6) and to this end thecoherer is adjustable relative to the pendulum, the adjustment beingafforded by a U-shapedbracket m carryingthe coherer, the bracket beingin turn seciired to a bar m slidable laterally relative to the pendulumin a groove or guideway m of a block M supported upon a bracket Msecured tothe back-board or plate A.

Secured to the block M are also two binding posts N, N, .to the formerof which is secured a wire n connect ing the same with one of theterminals t of the cohcrer, and to the latter of which a similar wire 7Lis secured, the other end of the last mentioned wire being'connected tothe opposite terminal of the coherer. From these binding posts one wire1t leads to a post 0 of the relay magnet P, and thence to the bindingpost 0 of the battery series G; and a second wire 12 leads tothc secondbinding post 0 of the relay battery series P' (Fig. 1), and also throughthe fourth-post o to ground. A wire 1 also leads from the post N to alarge metallic collecting plate Q (Figs. 1, s and 11 which is in turnproperly connected with a vertical wire Q commonly used in theso-called'wireless telegraphic systems, the

upper portion of this wire projecting 'aerially to intercept and receivethe action of the waves created at the I transmitting station, andconduct the electric impulse '110 down through the large metalliccollecting plate and the wire q, post N and wire ate the one terminal ofthe coherer, theopposite terminal thereoflleading to the relay batteriesin the'inanner before mentioned.

The hand setting mechanism may now be considered, 1 1 5 and inthisconnection Figs. 2 and 3 will probably be of most assistance. I 4

R is a magnet in-the localcircuit (dotted arrows Fig.

- 12) adapted to be energized when the coherer has been .duly affectedby the spark or other influential excitement caused by the main ormaster clock, which closes the relay (same figure), the armature of therelay clos- 1 ingsaid loc'al circuit.

R is an armature pivoted at rand arranged to be attracted by the magnetB when the sameis energized, but normally held therefrom, while saidmagnet isdeenergized, by a spring-elevated arm S, said springbe ing" ofthe bowedtype'iifdicated by s and secured at s to the clock-worksframeB, the free end of the'spring projecting througha slot 3 in the arm S,as does also the free endot the armature R, The outer end of the arm Smounted in posts tprojecting from the front plat of the frame B. At apoint intermediate the ends of the rock-shaft a depending fixed arm U issecuredfthis arm in turn being pivoted to a loose sleeve u slidablelongitudinally of the arbor or shaft d of the seconds hand. The forwardend of the sleeve u is formed into a cam u arranged, when in operativeengagement to oppose a correspondingly shaped but directly oppositelydisposed cam 11. formed upon the rear end of a sleeve 'ufcarried by theseconds-hand. The secondshand is normally held sufficiently fast to itsshaft d to be turnablo therewith through the medium of a spring (1coiled around the reduced forward end of said shaft, and being backed bya nut a exerts a constant pressure against the hand to secure a holdingfriction between the contiguous endsof the sleeves u and a shoulderconstituted by enlarging the shaft d slightly as at d, it being overthis enlarged portion that the sleeve is reciprocates. It will thereforebe seen that as soon as the armature R is attracted b itstmagnet itsfree end contacts the base of the slot in. the arm S and forces the armdownwardly (see airow Fig. 2) against the tension of the spring 5, (samefigure), whereby the lower end of the depending arm U will be thrownforwardly carrying therewith the sleeve u, and the cam end of the lattercooperating with the cam end of the sleeve u will sufficiently overcomethe normal friction between the parts to shift the sleeve 11? and handto a predetermined central or synchronized position. Simultaneously withthe denergizing of the magnet R the parts will be restored to theirprimary positions by the spring s when the seconds-hand may rotate asusual with its operating shaft.

A rearwardly projecting stub 11 is also affixed to the rock-shaft T in amanner to move therewith to raise or lower, as the case may be, a rod Vpivoted thereto at its upper end, as at v, and at its lower endcorrespondingly secured to lever W pivoted at w to the frame B andfurnished at its free end with a V-shaped lug w adapted under certainconditions to coact with the inclined walls bordering a similarly shapednotch 10 in the periphery of the disk f for centering or synchronizingthe minutes-hands D. The disk is rigidly secured to the inner end of asleeve 10 (Fig. 3), the opposite end of said sleeve carrying theminutes-hands. Thissleeve w'- is mounted upon and normally rotatablewith tlfe shaft or arbor F, adequate friction between the parts forthatpurpose being created bythe spring spider w arranged to exert itsforce against the disk f (Fig. 2). When, however, the lug 10 engages theinclined walls of the notch 10 in the disk, incident to the downwardthrust of the rod V and lever W when the rock-shaft T and its stub o isactuated by the retraction of the armature R by its magnet R, thetension of the spring spider 20 will be temporarily overcome to permitthe disk together with its sleeve 10 and the minutes-hands to rotateindependently of the operating gear train to bring said minutes-handsalso to a predetermined central or synchronized position. The lug w willbe retracted from the notch w in an obvious manner immediately upon thedeencrgizing of the magnet lt.

The operation of the system may perhaps be more readily followed byreference to the diagrammatic is rigidly secured to the end of arock-shaft T views, and firstly to the transmitting station, asillustrated in Fig. l0;X designates a controller which may be arotatable disk operatively connected with the time-works of a master ormain clock to which all other clocks of the series to be synchronizedare subordinate. This disk carries a pin 00 arranged to engage the freeend of a pivoted switch at to closethe primary circuit as, one terminalof which connects with said switch while its opposite terminal connectswith a leaf spring contact x Y is a Ruhmkorff induction coil, thesecondary circuit x of which, when the primary circuit is closed by themaster clock, generates a spark of predetermined codal character inharmony with the receptive means for the waves or impulses radiatingfrom said spark.

In Fig. 11 which shows the circuit in general at the receiving station,.Q is the vertical wire; Q the metallic collecting plate; Z the coherer;P the relay circuit, P the relay magnet, and G the relay batteries. Itwill be noted that the wire q runs from the collecting plate Q to oneterminal of the coherer, while the wire n runs from the other terminalto ground, and also that each coherer terminal connects with oneterminal of the relay circuit P, so that when waves of the proper codalcharacter are intercepted by the vertical wire, collecting plate Q andwire q and transmitted to the coherer the desired influence is impartedto the coherer to complete the relay circuit, whereupon the armature pof the consequently energized relay magnet P will be attracted tofacilitate the operation of the mechanism requisite for theaccomplishment of the ends desired herein, illustrated more in detail inFig. 12, in which both the transmitting and receiving stations areillustrated, the former being the same as shown in Fig. 11 with some ofthe parts occupying a somewhat different relation owing to the changedposition'of the controller disk and its pin. The armature of the relayhaving been attracted as suggested in. connection with Fig. 11, we willsuppose that the disk f has rotatedto an extent sufficient to establishelectrical communication at the point 3. This will complete a circuitthrough the relay batteries, wires f g and g, as shown by full linearrows, which will include the winding means of the clock, whereuponsaid winding means will operate in the manner set forth in the Pondpatent hereinbefore disclaimed. If, on the other hand, we assume thatthe disk f is in its alternate position establishing electricalcommunication at the point 4, then the closed circuit will follow thecourse of the dotted arrows and energize the magnet R to actuate thehand setting mechanism.

The controller disk X may be designed to operate at any desired times,that herein being described adapted to make and break contact at thetransmitting station every half hour, and its rapidity of rotation ispreferably twice that of the disk f at the receiving station, wherebythe hand setting mechanism and the winding mechanism will be alternatelyoperated every hour, the time of operation of the former being on thehour, and that of the latter on the half hour.

In Figs. 13, 14 and 15, the coherer shown comprises a sealed glass shell2, constituting a casing, an inner glass tube 2, and the terminals 3 and3 fitted to and projecting into said tube, the metallic powder 3 beinginterposed therebetween. The agitator comprises the shaft k andstar-wheel k, the means for operating the same M thereby imparting thedesired movement to the star-- wlicel.--

Another hirm of the coherer is that illustrated in Fig. .16, thecharacteristic feature of which resides in the fact that the tube isrotatable relative to the agitator rather than vice versa as in thepreceding embodiments. In this figure, 6 is the glass tube, 7, therein,8 the metallic powder, the star-wheel agitator and 9 the operating shaftthereof. The tube is loosely mounted in rings 10, secured to thesupporting standards ll and projecting outwardly from one end. of saidtube is a crank 12 arrangcd to project between the ends of the clip 1carriedby the pendulum stem'L, in the same manner that the crank Zprojects between said ends of the clips in Fig. 6. The result of thispresent construction is that as the pendulum vibrates, the crank willrotate the tribe 6 in the rings 10, and to effect the agitation of themetallic particles which of course shil't slightly with the tube, thestar-wheel is held practically stationary by a depending weight 9.'atthe outer end of its shaft 9, thc constant tendency of said weight beingto maintain its center of gravity. i I desire it understood that myinvention embraces the utilization of metallic cases, frames or. facesof clocks, alone or otherwise, as receivers, and that they may beloo-med or arranged to constitute a plurality of such receivers.

For the want of better terms, I employ in the claims such expressions asoperable through space and transmitted through space, meaning thereby todenote the absence, partially or wholly, of tangible conductors, suchaswircs, etc.; also codal disturbances meaning thereby a wave and anyother variance from a normal or natural condition, created in accordancewith a predetermined plan to be in harmony with the instrumentalities atthe receiving stations or subordinate clocks, whereby the system will beinoperable by stray waves, etc. I

The coherers herein described will notdaeclaimed because they moreproperly constitute the subjectmatter for a divisional application.
